CLOTH-WINDING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 759,376, dated May 10, 1904.

Application filed November 1, 1902. Serial No. 129,682. (No model.) i

To all whom, it may concern:

Be it known that I, NELSON J ARVIS, a citizen of the United States, residing at J ewett City, in the county of New London and State of Connecticut, have invented new and useful Improvements in Cloth-Winding Machines, of which the following is a specification. This invention relates to cloth-winding machines; and the object of the invention is to provide an effective machine of this character having simple means for effecting the transfer of the cloth from a filled or completelywound board to another or empty board, so that the former can be taken from the machine and an empty one put in its place while the latter is having the material wound thereon, by reason of which the output of the machine is materially increased. The improved machine involves a plurality of independent board-carrying devices, and although in the following description I refer simply to two this number, if desired, may be increased.

In connection with the independent boardcarrying devices I provide a pair of guiderolls between which the cloth to be wound upon the boards is adapted to travel, and a suitable registering device is preferably connected with one of these rolls and is adapted to indicate the amount of cloth wound upon the boards. The two rolls mentioned are preferably arranged substantially between the board-carrying devices, and when one board has been filled the cloth between the same and the rolls can be out, so that the leading end of such cloth can be transferred to the other board.

The board-carrying devices are simple, having means for efliecting the ready removal of the filled boards and as easily the attachment of the empty boards.

In the drawings accompanying and forming part of this specification I have shown the invention in one simple and convenient embodiment thereof, in which- Figure 1 is a side elevation of the machine. Fig. 2 is a vertical sectional elevation of the same. Fig. 3 is an elevation as seen from the right in Fig. 1. Figs. 4 and 5 are detail sectional views hereinafter more particularly described. Fig. 6 is a detail in sectional elevation of part of the registering mechanism.

Like characters refer to like parts in the several figures.

The framing of the machinemay be of any suitable character. That represented includes in its construction the columns or uprights 2, arranged vertically and in parallelism and having widened base portions 3, to which the horizontal bed-plate 4 is bolted or otherwise fastened. The bed-plate 4, as will hereinafter appear, carries the cloth-winding mechanism.

Upon the lower ends of the columns 2, at the side thereof opposite that provided with the widened base portions or feet 3, are suitablyconnected brackets 5, adapted to rotatively sustain the rolls 6 of cloth to be measured. The pressure-roll 7, also carried by the brackets 5, serves to prevent wrinkling of the fabric as it is unwound from the roll 6.

The cloth passes from the roll 6 between the rolls 8, located above said roll 6, and hangs from the latter in the case 9, which protects it, and is then carried upward along opposite sides of the superposed horizontally-arranged guide-bars 10, connected with the columns or uprights 2. The guide-bars, which are disposed in parallelism, insure the proper feed of the material.

The fabric after it leaves the guide-bar 3 is carried'upward and around the guide-roll 11, rotatively supported between the columns 2, and then downward and beneath the guide-bars 12 in horizontal alinement, one of said guidebars 12 being connected to the columns 2, be tween the same, and the other being supported by and between the side members of an auxiliary frame upon which the different parts'of the winding mechanism are sustained.

The fabric after it leaves the guide-bar 12 on the right is carried upward between the rolls 13 and 1 1, the roll 14 constituting a measuring-roll, as a register, hereinafter more particularly described, is connected with the same.

The roll 13 constitutes a pressure-roll, its pur pose being to hold the fabric firmly in contact with the periphery of the measuring-roll, so as to secure the accurate registration of the cloth passing in contact therewith. The cooperating rolls 13 and 14 are supported between the board-carrying devices, hereinafter more parends of said shafts being carried by an arm 16 upon one of the columns 2. A second plate 17 is shown, it being in parallelism with the other plate and having a deep diagonallydisposed aperture or slot 18 into which the rolls 13 and 14 are let. The plates 15 and 17 are mounted upon the bed-plate 4 and constitute an auxiliary frame for sustaining the winding mechanism, and as the shafts of the rolls 13 and 14 are mounted simply upon the plate 15 it will be apparent that the plate 17 can be freely moved toward and from its companion without coming in contact with the said rolls, the aperture or slot 18 permitting this result.

I will now describe in detail one of the boardcarrying devices, and as they are the same in construction such description will answer for both. Upon the top of the plates 15 and 17 are rotatively mounted the stub- shafts 19 and 19, to which the gears 20 or other powerdriven members are suitably fastened, the hub 21 of one of the gears being rotative in the hearing which sustains the stub-shaft 19. A pin 22 extends radially of the hub 21 and its inner end fits in the longitudinal channel or groove 22 in the periphery of the stub-shaft 19, by reason of which it will be seen that said stub-shaft is free to have a sliding movement through the corresponding gear. Upon the inner ends of the said stub-shafts are suitably fastened the collars 23, having the elongated jaws 24, in the inner faces of which the grooves 25 are formed, said grooves being V-shaped in cross-section. The board 26 is carried between these jaws and the ends of the board are of a shape to agree with the grooves 25, into which they are adapted to fit. Pinions, as 27, suitably fastened to the shafts 28, mesh with the gears 20, hereinbefore described. The shafts 28 fixedly carry upon one end thereof the pulleys 29, adapted to be simultaneously driven by a belt 30, actuated from the driving-pulley 30, said belt also traveling in contact with the idle pulley 30".

It will be assumed that the cloth after it has passed the rolls 13 and 14 has been applied to the board 26 between the upper pair of jaws 24, as shown by full lines in Fig. 2, and that said board has been filled with such cloth and that the lower board 26 is empty. To transfer the cloth onto the lower board, the following operation takes place: The shafts 19 and 19 are stopped by shifting the belt 30 from the pulley 30 onto a loose pulley, (not shown,) after which the cloth is cut on a straight line at some point between the filled board and the pressure-roller 13. The leading and free end of the cloth is then placed upon the lower and empty board, as shown by dotted lines in Fig. 2. The upper or filled board is then removed and an empty one inserted in its place, after which the belt 30 is moved onto the pulley 30 for the purpose of again simultaneously actuating the two board-carrying mechanisms.

Brackets, as 40, extend from the columns 2 and carry rotatively between them a screw or worm shaft 41, having at one end a pulley 42, adapted to be connected to a similar pulley 43 upon the shaft of the roll 14 by means of the belt 44. The brackets also sustain above the shaft 44 the bar 45, which slidably carries the nut 46, adapted to engage nor mally the screw-shaft 41 to be actuated thereby, the nut of course sliding longitudinally of the bar or shaft 45. Said nut is provided with an angular arm or extension 46, having at its outer end a depending finger 47, adapted to cooperate with a plate 48, connected to the outer ends of the said brackets 40, and the outer face of which is graduated to represent yards and fractions thereof. As the shaft 41 is rotated by the connections hereinbefore described with the guide or measuring roll 14 the nut 46 is moved along the shaft 45, the finger 47 being carried therewith and traveling adjacent to the registering-plate 48, so as to indicate the measurement of the cloth wound upon the respective boards. hen the nut 46 reaches the end of the screw-shaft 41, it can be returned to its initial position by disconnecting the same from said screwshaft, and this result can be accomplished by lifting the finger-piece 49 upon the outer end of the angular arm 46.

It will be remembered that the stub-shaft 19 is slidably connected with its gear, and I provide means for normally maintaining the two parts in rigid relation, so as to firmly hold the board in place. Upon the inner side of the gear 20, through which the stub-shaft 19 passes, is fastened the spring 33, having between its ends the tooth 34, adapted to be normally seated in a notch or recess 35 in the stub-shaft, whereby the latter is held against endwise movement. The spring 33, which, it will be understood, is in the nature of a latch, terminates at its free end in a finger-piece 36, which can be engaged so as to lift the tooth 34 out of the notch 35, thereby freeing the stub-shaft, so that the same can he slid outward to carry the jaw 24, connected with said stub-shaft, away from its companion jaw to permit the release of a filled board held between the same. One end of an empty board is placed in the channel of the relatively fixed jaw, after which the stub-shaft 19 is slid inward until the opposite end of said board is fitted into the channel of the movable jaw, at which point the tooth 34 will automatically spring into the notch 35. As the columns 2 are comparatively high, it will be seen that there is brought to view upon one side of the machine a considerable expanse of the fabric, by reason of which the same can be properly examined for the purpose of discovering defects therein.

It will be understood that the side plate or standard 17 is adjustable toward and from the companion plate or standard 15 in order to adjust the said plates to the widthof the cloth to be wound upon the boards.

The improved machine is simple and effect-- ive, and it can be inexpensively made, and by its use I am able to increase the output over machines of the ordinary kind when no provision is made for transferring the cloth from one removably-mounted board to another, and said improved machine, it will be obvious, ineludes in its organization independent devices for rcmovably carrying boards on which the cloth is to be wound and guiding means for the fabric or cloth, such guiding means being intermediate the board-carrying devices.

The invention is not limited to the exact construction hereinbefore described,for many variations as to the same may be adopted within the scope of my claims.

Having described my invention, what I claim is- 1. In acloth-winding machine, the combination of a plurality of devices for removably carrying cloth-receiving members, a powershaft, connections between said power-shaft for positively rotating the cloth-receiving member in a cloth-winding direction, and guiding devices for the cloth interposed between said members for guiding the cloth alternately onto the said members.

2. In a cloth-winding machine, the combina tion of independent cloth-winding members, means for positively rotating them, and clothguiding devices intermediate said members and adapted to serve alternately therewith.

3. In a cloth-winding machine, the combination of a pair of stub-shafts, each provided with a jaw at its inner end, a driven member through which one of the stub-shafts is slidable, a pin connected with said driven member and fitting in a longitudinal groove in said slidable stub-shaft, and a latch upon the driven member adapted normally to engage the said,

stub-shaft and to hold it against endwise movement.

4. In aeloth-winding machine, the combination of a pair of stub-shafts each provided with a jaw at its inner end, a driven member through which one of the stub-shafts is slidable, a pin connected with said driven member and fitting in a longitudinal groove in said slidable stub-shaft, and a spring-latch upon the driven member adapted normally to engage said slidable stub-shaft and to hold it against endwise movement.

5. In a cloth-winding machine, the combination of a pair of stub-shafts each having a jaw at its inner end, a driven member through which one of the stub-shafts is slidable, a pin connected with said driven member and fitted in a longitudinal groove in said slidable stub-- shaft a spring constituting a latch, upon said driven member having a tooth to enter the notch in said slidable stub-shaft to thereby normally hold the same against endwise movement.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

NELSON JARVIS.
